Chapter 95 Preparation before blasting (Please recommend and collect) Now
that we have the wooden bucket, the remaining part is the cart. The most important part of the cart is the wheel, but it is too troublesome to make. The load capacity of the cart must be very high, and it is not appropriate to use the arrow shaft as the spring, so Luo Chong gave the wooden pig two sets of data and asked them to make it.
"Make four wheels according to this size, two large and two small. The wood must be strong, and there must be no scars or tree eyes in the middle, otherwise it will break easily." Luo Chong handed a wooden board with two sets of data written on it to the wooden barrel.
"Well, no problem, we will pay attention." The wooden barrel looked at the numbers, took out a copper ruler, compared it with the scale on it, and then said that he understood.
It takes a lot of time to make the big wheel. Luo Chong didn't have time to wait for them, so he continued to busy himself.
The mud shell wrapped in pyrite has been burning for eleven days. It's almost time, so Luo Chong started to prepare other things.
In addition to nitric acid, the most important component of nitric acid is glycerin. The preparation of glycerin requires mixing soda and oil to make it saponify, and then decompose into stearic acid, that is, soap, and the other part is glycerin.
Soda is soda ash, but Luo Chong only has a bag of natural soda fragments, which need to be purified before use.
There are two ways to purify natural soda. One is to calcine first, then dissolve, filter, evaporate and crystallize; the other is just the opposite of this process, dissolve, evaporate and crystallize first, and then calcine. However, without high-precision equipment, the second method cannot be done, because in the final calcination process, soda ash will be decomposed by heat to release a large amount of carbon dioxide, and then it will be scrapped, so Luo C usedhong the first method.
Put the fragments of natural soda in a crucible and heat it. After burning, take it out and smash it, then put it in a bucket and dilute it with water to dissolve it, then clarify and filter it, and finally put the filtrate in a pot and boil it until it evaporates completely, and then soda ash crystals will precipitate in the pot.
Luo Chong had two vats of lard brought out and then put them on the fire to melt. This was the bad thing about animal oil. After cooling, it would solidify into a paste. Unlike vegetable oil, it was always liquid and would only freeze when it was very cold in winter.
After the two vats of lard melted, they were allowed to cool slightly. Soda ash was added before it solidified again. Stirring it with a wooden stick, the oil would soon become a viscous paste. At this time, the semi-finished products were poured into a square pottery mold.
After standing for a while, the oil would separate into two layers. The bottom layer was solid stearic acid, which was a large piece of soap. The top layer was covered with a layer of light yellow glycerin. This was what Luo Chong wanted.
The saponification reaction of the oil produced very little glycerin, only 5% of which was glycerin. The other 95% was soap. After the two vats of lard were wasted, the glycerin obtained only filled a jar as big as a human head. Moreover, such glycerin was still unusable and had to be distilled into concentrated glycerin.
Luo Chong brought a set of distillation equipment, poured glycerin into the distillation pot, covered it with a lid, connected the air pipe, and finally placed a jar at the outlet, and then sealed all the joints with wet mud, and finally burned a fire to heat it.
The heated glycerin vapor was re-condensed through the condenser tube and turned into drops of concentrated glycerin flowing out. In the end, only half of the jar was collected, and only 2/3 of the previous one was left. The preparation of glycerin was completed.
The tribesmen were very puzzled. They often saw the leader burning something during this period. It was not salt refining, pottery burning, or copper refining. It took a lot of time, and finally a bunch of things that they didn't know what they were for were made. They didn't let people touch them, saying that they were poisonous. This is going to turn into Breaking Bad.
The rat witch was completely confused. The elder knew a little bit. He knew that Luo Chong would have a new invention every time he burned something. This time he burned for half a month. What he got in the end must be incredible. This is a magical artifact prepared for opening the mountain.
In fact, it is not wrong to understand it this way. Of course, what you get in the end is amazing. It's a big deal. How can it not be amazing?
On the thirteenth day of the pyrite reduction, the reaction finally ended. Luo Chong dug personally open the burnt mud shell. The iron sulfide inside had turned into particles of iron sulfate crystals, the alumina turned into silica and aluminum sulfate, and the straw and firewood turned into carbon slag and ash.
Put these things in a bucket to wash, wash off the ash and carbon slag, and then pick out the black iron sulfate crystals. Silica and aluminum sulfate are stored separately.
Put the obtained iron sulfate crystals into the prepared distillation pot, connect the pipe and condenser, and start to burn again.
Several people watched Luo Chong burning there. It has been burning for so long, and they also want to know what comes out in the end.
The distillation pot kept making noises, and a large amount of steam began to come out. The cold water in the condenser interlayer soon turned into hot water. Luo Chong could only continue to add cold water to cool it down. At the final exit, drops of colorless and transparent liquid dripped into the jar, which surprised the people around.
Did the water come out from the water pipe above?
The Rat Wizard couldn't help but stretch out his finger, wanting to catch a drop of "water" at the exit to see what it was, and he scared Luo Chong at that time.
"Don't touch it." Luo Chong was so scared that he shouted and grabbed the Rat Wizard's hand. The Rat Wizard staggered and sat on the ground.
The Rat Wizard was very puzzled and a little angry. He felt that Luo Chong didn't treat him as one of his own tribesmen and was still on guard against him, and refused to teach him these magical techniques.
"Well, are you okay? This thing is very dangerous. You can't touch it directly with your hands. It will burn your hands." Luo Chong saw the Rat Wizard's unhappy expression and explained quickly.
"Can a drop of water burn your hands?" The Rat Wizard obviously didn't believe it.
"Really, there is no need for me to lie to you. If you don't believe me, just look at it."
Luo Chong used a clay pottery spoon to dip it in, then took a piece of firewood and dripped a drop on it.
Chi -
a drop of sulfuric acid dripped on the wood, making a chi sound, and the wood was quickly corroded and burned through.
The rat witch, the elder, and the cripple were stunned. What the hell, what did I see?
"Did you see it? If you stretched your hand over just now, you would be the same as this wood. It's not that I don't let you touch it, but this thing is really dangerous." Luo Chong explained to the others.
The Gulu Rat Witch swallowed a mouthful of saliva, obviously scared. If Luo Chong hadn't reacted quickly just now, the consequences would have been almost the same.
"Chief, why is this water so powerful? Do you want to use this water to burn through the rocks on the mountain?" The elder asked in confusion.
"This is not water, this thing is called sulfuric acid, which is also made from ore. What I want to make is not yet ready. This sulfuric acid is just one of them." Luo Chong explained.
"It's not done yet, so what will be more powerful than this acid?" The lame man asked in surprise and curiosity.
"Haha, it's almost done. It will be done tomorrow. You can see for yourself whether it is powerful or not." Luo Chong said with a smile.
The process of distilling iron sulfate was repeated several times before it was completed. There was really too much pyrite, and the iron sulfate obtained in the end was not small.
After the iron sulfate was distilled, it was decomposed into sulfuric acid and reddish-brown powdered iron oxide crystals, which were collected by Luo Chong separately. In the end, two large jars of sulfuric acid were obtained, and the iron oxide crystals weighed more than 100 kilograms. This is iron powder, which can be used to make some ironware.
With sulfuric acid, nitric acid is easy to deal with. Take out a new set of distillation equipment, put the saltpeter purified by the women and sulfuric acid into the distillation pot for distillation, and finally get nitric acid.
With nitric acid and concentrated glycerin, everything is ready. Just mix these two things. Hehe, but Luo Chong doesn't dare to do it now. If they are mixed together now, it is estimated that the entire Han tribe will take a plane to the sky.
Nitroglycerin is a highly sensitive liquid explosive that is almost impossible to store. The best way is to temporarily mix it before use because it is too sensitive.
How sensitive is it? Basically, it will explode if it is shaken. Burning, high temperature, or impact, large shaking will directly explode. It is better to separate them when not in use.
